tising indicia or decorative material thereon.

Another important object of my invention is to provide a shade structure in a device of the aforementioned character which is provided with side panels carrying display matter thereon; the said panels being hingeably and adjustably secured within an angular ambit so as to permit variable dissipation or emission of light rays in various directions.

A still further object of my invention is to provide a device of the aforementioned character in which the light emission means is provided with universal limited adjustment compositely operating in a horizontal plane and adjustment in a vertical plane'to the said horizontal plane.

A still further object of my invention is to provide a display and illuminating device of the aforementioned character which maybe mounted on a telescopically constructed standard to permit adjustment of the said lamp means to bridge lamp position or to a table lamp position.

A further object of my invention is to provide an illuminating and display device of the aforementioned character which has very low current consumption, and is very economical to operate at the .same time providing a rather simpleelemental arrangement of parts so as to permit manufacture economically in quantity produc tion.

Other features, ancillary advantages, and objects resident in my invention will be "readily understood by those familiar with the art, upon examination of the accompanying drawings which bear further elucidation in the ensuing description, wherein like parts are designated by like symbols, and in which;

Fig. 8 is a front View of my invention showing the vertical adjustments thereof and also the adjustments of the standard to make it adaptable for use as a bridge lamp or as a table lamp shown in dotted lines.

Fig. 9 is an end view-of Fig. 8.

Referring to the various figures, which illustrate the shade structure for the fluorescent lamp, and to the various other views, my invention is generally designated 10.

The shade structure is generally designated I l and consists of two side panels 12 and I3 and two end panels 14 and 1-5. The said side panels 12 and i3 and the end panel [4 are suitably cut out and have positioned in the said out out portions either illustrative matter, or matter carrying advertising representation designated I! for the side panels, and I8 for the front end panel it. The rear panel 15 does not diffuse any light but is rather utilized for securing the standard and the various other elemental structures tomake up the composite structure.

The current is supplied by a source of supply 19 to "which are connected, in series, a series ballast for a l'5-watt fluorescent lamp, or any other suitable similar structure or instrumentality, and is generally designated :Z'ii. In series, is also connected the starter 2.! and the fluorescent lamp 22; the entire circuit being provided with a suitable connecting plug for attaching to a receptacle, .and a switch element .23 for turning the lamp on and off.

The end panels I4 and I5 are secured by strut means :50 and SI which are arcuately formed at 52 and secured at 53 so as to form a rigid construction. Thus the framework will be rigid and permit the side panels 12 and iii to be adjustably positioned therein as will follow from the description of Fig. 9.

The limited universal adjustment is provided by the elemental structure indicated in Figs. 5, 6 and 8. In Fig. 8, the standard, or base, 24 may assume any number of positions by virtue of vertical adjustment by means of the telescopic tubular structure 25, 26 and 28 using suitably knurled locking means 29 and 21 to adjust the same to convenient heights to function as a bridge lamp or as a table type of lamp.

The upper tubular structure 28, or element, is provided with a reduced extension 30 to which is secured the channel element 3| by means of screws and nuts 33 or any other suitable fastening. The companion bracket 32 is utilized to clamp the same firmly in place on the reduced extension 30. To the bracket 32 an angular electrical binding post support 34 is secured in order to provide the connection means 35 for the wiring.

The channel 3| as indicated in Figs. and 6 has secured thereto the elbow element 36 which has an extension 38 attached securely by a nut or other locking means 31. The extension 33 and piping section 39 articulately secured at points 40 and 60 form a universal joint.

The piping section 39 is pivoted at 40 to the extension 38 whereas the plate element 4 l, which is secured to the end panel [5, is also provided with cars 59 articulately secured at 59 so that by the motivation of the points of articulation 60 and 49 a limited universal movement will be afforded as indicated in Fig. 8 where the dotted lines show the vertical adjustment, whereas in Fig. 3 the horizontal adjustment is indicated by dotted lines.

The means for setting the lamp in adjustment, vertically, are illustrated specifically in Fig. 5 where it is shown that to the plate 41 a connecting bracket 43 is secured by means of screws 44. The bracket 43 is provided with a clearance slot 68 to permit the bent portion 69 to operate therein. The angular extension 45 is folded over to form an angularly bent portion 43 which is suitably threaded in order to receive the threaded adjustment screw 41, which is provided with a thumb knob 48 so that it may be conveniently manipulated by the hand.

Intermediately the knob 48 and the body of the screw 41, a hemispherical equalizing portion 49 is shown. The said hemispherical element 49 operates against the outer surfaces of the bracket 43 when the screw is turned right or left to eifectuate the vertical adjustment indicated in Fig. 8.

Another important feature of my invention is illustrated in Fig. 9 where it is shown that the panels l2 and 13 are provided with trunnionlike extensions 6| at one end and 66 at another end.

The end plates 14 and are provided on opposite sides with a bearing bore 65 and a slotted portion 84 so that either trunnion 3! or 36 may be inserted into the bearing bore 65 and then allowed to slide into the slotted portion 64 as indicated in Fig. 9.

A series of stops 62, 63 and 64 are provided so that the sections I2 and I3 may be angularly adjusted as shown by the dotted lines in that view.

The Vertical tilting adjustment structure is connected to operate the display shade structure generally designated II by means of a bracket 42 which is secured articulately to the channel 3i and, in turn, secured to the extension 45; thus, when the threaded portion 41 of the screw is advanced in the threaded opening of the angular portion 46, it will cause the display shade ll to move upwardly in a vertical direction, and

when the thread is rotated in an opposite direction it will cause the shade to move downwardly as indicated by the dotted lines of Fig. 8. The universal joint 38, 39 cooperates with the articulately connected bracket 42 in concert with the equalizer 49 to efiectuate limited universal adjustments of the lamp shade structure H.

Thus it can be seen that I have provided an illuminating and display device which will provide illumination upwardly, downwardly and forwardly and at the same time will utilize a minimum of electrical current, will not heat up, and will provide a neat and mellow light through the translucent advertising signs or pictorial illustrations H and I8. The same are mounted in an interchangeable manner so that either the display or the advertising matter may be changed from time to time.

It will also be noted that I have provided side panels which may be angularly adjustable so as to permit more rays of light to be sent upwardly and lesser light to be cast downwardly without affecting the emission of light laterally, or they may be positioned as indicated by the full lines so as to aiford less illumination in an upward direction and more illumination concentrated in a downward direction.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

Having thus disclosed and revealed my invention, what I claim as new and desire to secure by Letters Patent is:

In a display advertising device, universal adjustment means including a channel element, a tiltable unit having an end panel secured to the said channel element, an angularly formed bracket element provided with an angularly formed threaded lug portion andarticulately secured to the said channel element, a universal joint secured intermediately the said channel element and the said end panel, and a universal equalizing and adjusting screw threadably engaging the said angularly formed threaded lug portion providing limited universal movement to the said tiltable unit.

DONALD CHARLESTON.
